More data, might also help in determining if a house will sell quicker than another house. A lot of that depends on variables - sure. But more data can help target some of those variables and better understand some of the variables.

I'd disagree. It might tell you if you're in the right range, +/- xx%, but it doesn't necessarily help you determine what the value of the house is, or what someone will pay for it.

This is one of those places where staleness of data, along with the cumbersome amount of details that can, perhaps should be, and often aren't, can prevent one from easily determining a price.
